An block of mass , starting from rest, slides down an inclined plane of length and angle with respect to the horizontal. The coefficient of kinetic friction between the block and the inclined surface is . At the bottom of the incline, the block slides along a horizontal and rough surface with a coefficient of kinetic friction . The goal of this problem is to find out how far the block slides along the rough surface.
What is the work done by the friction force on the block while it is sliding down the inclined plane? Express your answer in terms of , , , , , and (enter theta for , mu_1 for , and mu_2 for ).
